Correct answer: A — Switch to beta-blocker carefully titrated; avoid combining nondihydropyridine CCB with beta-blocker

Avoid combining beta-blocker with nondihydropyridine CCB due to bradycardia; choose one class and titrate. Adding digoxin (B) may worsen bradycardia; outpatient amiodarone (C) is not first-line rate control; ivabradine (D) not indicated; no therapy (E) leaves symptoms.
